Most of my gripes about unnecessary gubbins relate to the OS and UI.
Just to make clear, this isn't meant to be a "what's wrong with S60" article.
This article is actually about mobile phones in general, regarding features which used to serve a purpose but are now no longer useful. Even Visual Radio isn't an S60 topic really, it's available on cheap Series 40 models too and is platform independent.
Discussing which apps belong in S60 is something for a totally different article, and I think it's been covered quite a lot on AAS anyway.
mainly the fact that USB ampere is too low to be really "decent" in charging anything (you cannot fast charge through USB in comparison to a proper dedicated charger). Yes its good to have a standard "one size fits all", but
Actually you CAN use a dedicated charger with USB ports, the phone I mentioned in the article (the 8600 Luna) comes with a standard Nokia charger that has a microUSB plug on the end instead of the usual 2mm plug. Here's a photo of it:

If you switch to USB charging, you could charge through a computer or a normal mains socket, you would have the option of both. Without USB charging, people are forced to use mains sockets only.
That feature is the camera, I work with many companies who have corporate policies against cameras due to security concerns and you'd be hard pressed to find a good and feature laden smart phone that doesn't have a camera and that includes the Nokia E-series phones.
Most of the Eseries devices do come in non-camera versions for precisely the reasons you specify.
The E61 was only available without a camera, and the E60, E50 and E51 all have cameraless variants, so the devices are out there if people want to buy them.
The variants don't get advertised much though as they don't sell as well as the camera versions.
(Wi-Fi video is a) Brilliant idea, amazed Nokia hasnt seen this yet.
It is a really good idea, and Nokia do actually have it on their internet tablets, but officially it only works with Google Talk (and unofficially with Gizmo, but that's a tiny bit trickier to get working for the average user). Anyway, I've used it with GT and it is really great, I had some relatives in another country show me round their house which was pretty much the next best thing to being there. But alas it's only tablet-to-tablet, which severely limits its audience.
If they could put an easy to use wi-fi Skype video client on S60, including compatibility with Skype webcams on PCs and other devices, that would be a killer app right there. The hardware to use it would already be present on many many Nokia devices, all they'd have to do is offer it as a download and start integrating it into firmware.
